Europe remained on high alert as soldiers were deployed alongside police in Belgium to protect Jewish buildings and the head of Europol warned that further terrorist attacks could not be ruled out in the wake of the murder of 17 people in Paris by Islamist gunmen last week.
The move to guard potential targets in Antwerp’s Jewish quarter on Saturday was the first time in three decades that Belgian troops have been used to bolster police ranks. It follows the deployment of French soldiers following the attacks in Paris.
Thirteen jihadi suspects were arrested in Belgium on Thursday night in an operation that foiled a sophisticated plot to murder police, authorities said.
Belgium has increased its terror warning to three, the second highest, following the raids in which two suspects were killed.
